(INDIANAPOLIS) - A federal judge has ruled that Roger Hardin of Bedford will remain in federal detention for his alleged role in a scheme to steal more than $800,000 from Bloomington taxpayers through fraudulent concrete contracts with the city.

The judge ruled this way because 51-year-old Hardin is on parole after serving prison time for burglary and drug convictions, and because investigators say he tried to conceal his involvement in this new crime.

Former city of Bloomington project manager Justin Wykoff , who is also charged in the crime, will appear today at 1 p.m. in U.S. District Court in Indianapolis.

43-year-old Wykoff of Bedford remains in jail until his hearing on 24 counts of embezzlement by converting governmental funds for his own use and one count of conspiracy to commit a federal crime.

Hardin and his 25-year-old son, Zachary Hardin, each are charged with one count of conspiracy to commit a federal crime. The son, who has no criminal record, was released from custody after a court hearing Thursday.

Federal agents arrested all three men early Thursday and charged them with a plot overcharging the city for concrete work, some of it not even down by the men's Reliable Concrete Co., and then splitting the cash among themselves.

Court records indicate Wykoff has hired Martinsville attorneys John Boren and Glen Koch to represent him. Federal public defenders, Steven Allen and Sam Ansell, were approved Monday for the Hardins.
